re: The goal of many Gen Z and millennial women is now to be a DINK—dual income and no kids

My wife and I aren't able to have kids, and at this point we're embracing the DINK (I just learned this term last month) lifestyle. Fertility treatments aren't really an option for us for reasons I'm not going to get into. We were foster parents for a while but God damn that was hard on us and our families, and we have an excellent support system. We also had a real count of a DCFS worker assigned to us, which only made it harder. We considered adoption, but the costs of doing so made us both feel like we were gonna be buying a kid, and really turned us off from the idea. We may try fostering older kids when we're a bit older, but that's not set in stone. We aren't DINKs because of the reasons mentioned in the OP, but I'd be lying if I said I didn't enjoy our current lifestyle. We live in a modest home, much cheaper than we could afford, drive sub $50k vehicles, but we travel frequently and enjoy going to concerts and events, nice meals out once a week, charitable donations, and putting extra money away in retirement accounts and investments so we don't have to work until we die.
